Almost seeing the Light
It been a war getting all the bugs worked out of my so called buget build LOL.
Now I think I have a Bad EGR valve the car was running great but all a sudden it started running very poorly and some times just die.
I became hard to start idel ruf or just die.
Lack of bottem end power I think the EGR go bad and it not that old 1000 miles on it.
And the MPG are not that great.
I checked for vacume leaks so far cant find any retighen all intake bolts everything is tight.
Rechecked the timming still good.
Any other ideas before I pull the Plenum off to change the EGR valve.

Any codes?
The EGR would only be affecting the idle quality if it where stuck in the open position or leaking in the closed. Only when the EGR switch feeds it engine vaccum does the EGR valve get lifted up and pulled open. With no vacuum feed the EGR is rested in the closed position. If it's shut (no vacuum and not stuck) and sealing it's not affecting your idle.
Unplug the MAF and see if it runs better.
Then do the same with the timing EST connector on the firewall. Do one at a time.
If it runs better with the EST unplugged it's a timing issue. Is the balancer new?

The balancer is New.

Physically set the motor by hand to #1 TDC on the Compression stroke. See if the zero mark on your "New" balancer is aligned with the zero on the timing tab like it's supposed to. If it's not that piece of chit is your problem. Make your own temporary mark and set timing using that. See how it runs then.

Factory setting is 6 degrees. Still double check your new balancer mark. If it checks out at least you'll now be able to trust it. Good thing you didn't waste time taking things apart thinking it was EGR related.
